Standard coping profiles fail on modern EWI and ICF builds because they lack the deep reveal dimensions required to cover insulation layers. Protect wall boundaries from water damage.
A CAPPING THAT DOES NOT COVER THE FULL REVEAL LETS WATER IN. WATER IN MEANS CALL-BACK. CALL-BACK MEANS MARGIN GONE.
// Definitions
An **aluminium capping** (also known as a wall coping) is a precision-formed protective profile installed over parapet walls, window heads, wall boundaries, and EWI reveal edges to prevent rain penetration. Fabricated from marine-grade aluminium, made-to-measure cappings provide a seamless, corrosion-proof, and lightweight boundary seal. They allow for natural thermal expansion while ensuring that rainwater is shed clear of render systems, preventing staining, dampness, and structural cracking.

Protective head cills and drip-edge profiles installed above external window openings, throwing water clear of glazing seals.
Compatible with Knauf and SolTherm EWI render margins.
Configure Profile →Secret-fix coping cappings for flat parapet walls. Sliding joint splices allow silent expansion without breaking seal integrity.
Compatible with concrete blocks and structural steel decks.
Configure Profile →Extra-wide cappings specifically folded to seal top margins on external wall insulation facades.
Compatible with Baumit and Rockwool facade render coatings.
Configure Profile →Bespoke return bends, splayed angles, and corner profiles built from CAD details for irregular masonry structures.

// SEO FAQ
We fabricate custom aluminium cappings that interface precisely with Baumit systems. Our profiles accommodate varying reveal depths, providing a secure, watertight seal over insulation boundaries and preventing render cracking.
A capping (or coping) sits directly on top of structural boundary elements like parapet walls, window heads, and wall boundaries, sealing them against water. A flashing is a thinner, flexible profile installed at junctions, wall valleys, and roof intersections to shed running water clear of joints.
Yes. We supply custom made-to-measure aluminium cappings to builders and EWI contractors across all 32 counties of Ireland, with secure delivery to sites and yards.
Yes. All cappings are powder coated in-house using architectural-grade Polyester Powder Coating (PPC) certified to Qualicoat standards, matching window frame or cladding RAL codes.
